Hair Follicle Drug Testing - Lincolnton, NC

What it is, How it works

Hair analysis is recognized as a significant approach for detecting substance use, including alcohol. Through the trapping of biomarkers within the fibers of the growing hair, hair offers an extended history of alcohol and other substance consumption. When obtained near the scalp, hair can demonstrate a detection window of up to roughly 90 days for alcohol and other substances. Gathering hair is uncomplicated, fairly resistant to tampering, and conveniently transportable.

A 1.5-inch sample comprising approximately 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg of hair, which is the optimal for initial and confirmatory testing. For EtG, additional tests, and/or analyses exceeding 10 panels, a sample size of 150mg is advisable. It is suggested to use a jeweler’s scale for weighing the hair. If scalp hair isn't available, an equivalent amount of body hair can be used. Head hair specifically refers to the scalp hair, whereas body hair encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result is comprised of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the sample is initially incorporated into a laboratory’s system. This process ensures the appropriate sealing and delivery of the sample, allocates a random LAN (Laboratory Accessioning Number), and fulfills any supplementary data entry absent from an electronic chain of custody system.

Screening offers a preliminary evaluation for drug abuse. It effectively eliminates drug usage for most samples economically. However, a positive screening result requires confirmation for court acceptability. Any sample exhibiting a presumptive positive in the Screening phase necessitates subsequent validation.

Presumptive positives in Screening trigger the withdrawal of more hair from the original sample for Preparation in Extraction. In this step, substances are isolated from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), establishing hair drug screenings as complex procedures.

Verifying any positive screening outcome is executed using GC/MS, GC/MS/MS or LC/MS/MS. Prior to confirmation, all samples with a presumptive positive undergo washing as required. Every phase of the laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and certification to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug consumption up to 90 days, unlike the narrower detection period of urine tests.
• High accuracy: Hair drug tests are challenging to manipulate, enhancing the reliability of outcomes.
• Historical usage data: Hair analysis reveals drug usage patterns over time, not merely recent consumption.

Limitations:

• Inability to detect recent intake: Drugs become detectable in hair only after approximately 5-7 days.
• Expense: Hair drug testing generally incurs higher costs compared to alternative drug testing approaches.
• Result variability: Drug metabolite concentration within the hair may vary due to factors like hair color and individual hair growth differences.

Note: Commonly termed as "hair follicle tests", these tests actually analyze the hair strand and do not include the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing with urine tests in Lincolnton, NC, hair tests stand out for superior detection.
